Hi all I am wondering if some could point me to some good powders and loads for 155gr jhps for high velocity and accuracy for a stock Glock.20.sf .I have heard AA.#9 Is good along with power pistol and Alliants new BFE is good the two things I am looking for is velocity and safe pressures for my stock Glock.20.sf. thanks all for any tips
Which powder do you want to work with?
155 JHP
Accurate Arms shows this...
AA#No.9 14.3 grains @ 1244 fps
AA#No.9 15.9 grains @ 1414 fps 32,700 PSI (actually on the low side still)
Alliant BE-86 is a powder that I am looking for to test with myself.
BE-86 9.3 grains @ 1403 fps (Max load no pressure values)
Alliant Power Pistol shows a 150 JHP
PP 9.7 grains @ 1415 fps 35,600 PSI
My best estimate would be 9.5 grains @ 1390 fps
Thanks Shadow, I came on this forum because I get less repercussions asking on this board, by the way I did fire off the 180gr fmjs on top of 9.2 grains of Longshot ignited by CCI magnum primers with absolutely no over pressure sings despite some feed back by other folks ;D ;D
You're welcome HalfGlocked, I totally understand, I hate when things get twisted around with attitudes. When I was learning how to handload there wasn't an internet base of people that we could bounce ideas off of, or discuss what worked and what did not!
There are a few handloading and other gun related forum on Facebook but things can and do get muddy trying to follow what people are seeking and answers being provided.
One thing is for certain, I'm not too old or too lazy to try and learn new things... ;)
Thanks I have a new Lyman book when I got kit but it is a good ok I don't know about all the other loads the book doesn't have, nor do I have the experience yet with reloading especially with the 10mm, now I am trying to. Find some AA no.9 for
Lighter bullets , the only place I found that has it is Lohman , and the Haz mat shipping is more than 1# of powder the powder is 19.99 and shipping is 25.00$ +9.00 fee causing them to come out to 57.00$ for 1# does anyone have any other sources?
I use both Bluedot and Longshot for 150 grain JHP loads in my Glock 20SF. The accuracy is great with both powders with Longshot giving a slight edge in velocity.
Thanks Radominator, I do have longshot I just thought it was too slow for that light of a bullet .Now I'll do some more research.
Power Pistol is a good powder for moderate loads.
Vihtavouri 3N37 and/or 3N38 if you can find it. I'm shooting 165 Sierras at 1350 over 12 grains of 3n38.

Sorry I didn't eve realize I did not list powder(s) all I have or cold find is Longshot,and I was worried that 155grainers would ve too lite?
Well I finally went out and got to test out the last load of 9.2 grains of Longshot with CCI primers seated Ar 1.252 and Hornady 155 xtps and everything went well no ftf no bulging cases primers all good and I know the book doesnt show anything g below 180 grainers,I also know Underwood exceeds that by quite a bit,I just asking .for hints with any liability on who ever says it. But what would be a prudent next step up I. G20 SF with stock barrel?
I have seen loads past 10.0 with 155 and 165 grain HP's if you want to stay on the safest side 9.6 @ 1375 fps to 10.0 @ 1400 fps would be good to go with the 155 XTP's.
DT was at 9.4 with the 165 Rem GS
DT was at 10.0 with the 155 GD 1400
SF was at 10.2 with the 175 Silvertip 1375
UW was at 10.5 with the 155 XTP @ 1500
Thanks shadow ,and @UW they test these on Glock factory barrels with the factory chambers I believe. So I'll start @9. 7 grains of LS would you think that that it would be a safe starting point and step up.1 grain at time up to 10.0?of course checking casings as I go ?
I have shot a few hundred 155 XTPs using Bluedot. Lots of muzzle blast compared to other powders I have tried.

:D Blue Dot is vocal, without question. It does seem to like working with XTPs, though.

No doubt! My only issue with blue dot is that its hard to come by around here
Thankfully, Alliant pistol/shotgun powders of all stripes have been seen more regularly in my area these days. I have to say that I (thankfully) was reasonably well stocked going into this last shortage, so I never was in too terribly bad need of components.
Wow i have been off the forum for a while 'but it looks really nice!I apologize for digging up an old post but i just had to ask because it relates directly to my op 'so I have been great safe rests using 10.00 grains of longshot absolutely no problems as long as I stay with cci large primers would it be safe to try and step up to 10.5 like Underwood?Has anyone else done this with a stock G20sf unsupported barrel?Or should I just stay where iam at?
halfglocked, If you do decide to try this I would suggest you add 0.2 grains at a time a test while inspecting your brass for signs of excessive pressure, like flattened primers or smiled brass...I run non captive 22 lbs recoil setup on mine.
Who's to say how your lot of powder will perform using your method of loading for the given test. ::)
As you begin to push the limit, the cap will entirely be dependent on your conditions (gun / brass / primers / powder lot / box of bullets / temperature / phase of the moon / etc).
My conditions are not yours, but I stopped at 9.9gr LS w/ 155s.
Stay safe.
Okay thank you both for the feedback,iam thinking I will stay where iam at ,no issues no over pressure sings and the extra 100 fps isn't worth any kabooms.i did want to ask does LS have any flash suppressors in it?I ask because our church had a shoot out well into dusk and my loads didn't seem quite the signature some of the other pistols. Although louder.
One of the nice things about the 10mm is it is tolerant of many powders. My experience does not include nuclear type reloads. My idea of a max load is in the general area of what the Hornady book would call a max load. My experience between G20 & G29 (3 7/8" barrels up to 5 1/4" barrels) is with 155 to 200gr bullets.
For 180gr to 200gr loads I prefer Longshot. These are hunting loads to they are meant to run at max pressure/velocity. With the 5 1/4" barrel the Longshot gives me a very accurate 1,330 fps with the 180gr XTP and 1,235 fps with the Beartooth 200gr WFNGC bullet.
For 155 and 165gr bullets I prefer Power Pistol. It looses less velocity in shorter barrels than Longshot and is less sensitive to minor changes. 9.0gr of Power Pistol gives a bit over 1,200 fps with a 4 1/2" barrel and is an accurate easy shooter with either the 155 XTP bullet or the 165gr Gold Dot bullet. It is well under max, easy to shoot and still packs decent power. FWIW, I have tried CFE Pistol with most of these bullets and I find Power Pistol much easier to get good non max loads out of.
